The app utilizes Firebase as the backend for storing user-related data and implementing authentication functionality. Firebase offers a comprehensive suite of tools and services that simplify the development process and provide a scalable and reliable infrastructure.
Firebase's Authentication feature enables secure user registration and login functionality. Users can create an account using their email and password or sign in using their existing credentials. The app utilizes Firebase Authentication to authenticate users and manage their sessions.
Firestore, the NoSQL cloud database provided by Firebase, is used to store user-related information, such as profile details. It offers real-time synchronization and offline support, ensuring that users' data remains up-to-date and accessible even when the device is offline.
The following aspects of user data are stored in Firestore:
The "users" collection contains documents representing each registered user. Each document contains the following fields:
- User ID: A unique identifier assigned to each user.
- Name: The user's name or username.
- Email: The user's email address.
- Profile Picture: An optional field to store the user's profile picture URL.
Firebase Cloud Functions can be utilized for server-side logic and processing. While not explicitly mentioned, it can enhance the app by enabling additional functionality, such as order processing, notifications, and other backend operations.
The app consists of the following screens:
The splash screen appears when the app is launched and provides a visually appealing entry point for users.
The welcome screen greets users and provides an introduction to the app's features.
The login and register screens enable users to create an account or log in using their credentials.
The forget password screen allows users to reset their password if they have forgotten it.
